Those who have read The Fault in Our Stars (and if you haven't, it's really, really good) are most likely looking forward to the movie version of the book starring Shailene Woodley as Hazel Grace Lancaster and Ansel Elgort as Augustus Waters. Filming and producing a story about teen cancer is probably no easy feat. Case in point? Shailene having to cut off msot of her hair in order to play Hazel. And of course it's all on video.

Taken all the way back on August 16, 2013, but seemingly released recently, the video shows how the stylist who's working on Shailene's hair has to cut through multiple ponytails. Woodley covers her eyes and exclaims, "I might cry so hard, you guys!"

Who hasn't been in that position, feeling nervous and a jumble of nerves before an extreme haircut? Though Shailene has a noble cause for doing so ... and is relating to the patients she is portraying ... it's still nerve-racking nonetheless!

It must be devastating having to feel your ponytail get cut off multiple times, let alone just once. I can kind of relate: On a personal note, I once chopped off my 10-inch mane for Locks of Love. The process was the same -- but with only one ponytail. It was still incredibly scary (I know, it's just hair and it will grow back, but at times, so much of our identities are tied to our hair), and once I felt my stylist chop off that ponytail, I knew there was no going back. I'll never forget that feeling. And even though it was for a wonderful, generous, amazing cause -- I'd be quite hesitant to do it again. I guess I am that vain.

It seems Woodley also took an applause-worthy route by sharing on her Tumblr that she will donate her hair to Children With Hair Loss. "Not only do I have the opportunity to externally shift my current establishment of self, but I have the blessed gift of donating my long locks to a wonderful organization who will then create a wig for someone in need," she wrote. "What an honor."

Can't wait to see what Shailene looks like in character and kudos to her for braving the whole hair chopping off process. It will be well worth it and she maybe can now understand even more what her character is going through. And at least she didn't do anything like this:
